I noticed that the original posting on this topic is not linked into the
description.
I suggest the following update on this page
the topic could be:
Closing Roles.
Deborah McGuinness to draft. An initial limited description (with
follow-up discussion) is available from
the mailing list posting
http://lists.w3.org/Archives/Public/public-swbp-wg/2004Oct/0052.html
One of the benefits of working with a language that allows for open
world reasoning, is that reasoners do not make closed world
assumptions. Thus, it is sometimes important to state that there will
be no additional values filling a slot so that reasoners can make
inferences based on current values and their properties.
This note discusses approaches to the problem and provides examples.
